SNOW FENCE.

Application filed January 3, v1925. Serial 110.408.

vented certain new and useful Improvements in a Snow Fence, of which thefollowing is a specification.

This invention relates to improvements in fences and is adapted moreparticularly to One of the important objects of the present invention isto provide a fence-of the above mentioned character, which'will bepositioned parallel to a vhighway or road and spaced therefrom. 1nsuclra manner as to prevent snow from becoming banked on,

the road or highway.

A further object of the invention to provide a snow fence of the abovementioned character, whereinfthe pickets of the fence are of suchconstruction as to cause the neutralization of the air currents and windwhereby the snow will be prevented from being forced through the fencebetween the pickets onto the road.

A further object of the invention is to provide a snow fence of theabove mentioned character, which is of such construction as to permitthe same to be readily assembled or disassembled.

A further object is to provide a snow fence of the above mentionedcharacter, which is simple in construction, inexpensive, strong anddurable and furthermore adapted for the purposes for which it isdesigned.

Otherobjects and advantages of this invention will become apparentduring the course of the following description.

In the accompanying drawing forming a part of this specification and inwhich like numerals designate like parts throughout the same: Y

Figure 1 is a front elevation of the snow fence embodying my invention.

Figure 2 is an end elevation, and

Figure Sis a fragmentary top plan view.

In the drawing, wherein for illustration is shown the preferredembodiment of my invention, the numeral 1 designates generally asubstantially rectangular shaped frame forming a part of my improvedsnow fence, the same including the upper and lower longitudinal angleiron members 2 and 3 respectively, and the angle iron end members 4. Anysuitable fastening means such as is shown at 5 is provided for securing' the frame in an assembled position. If desired, angle iron bracingmembers may extend between the upper and lower longitudinal members andbe secured thereto'at their respective ends.

Secured to the upper and lower longitudinal members 2 and 3 of the frame1 are a plurality of fencepickets 6, the same being arranged .inparallel spaced relation and at a suitable distance with respect to eachother. The securing means whereby the pickets. are supported on theframe is shown, at 7. I

Each of the fence pickets 6 is constructed of galvanized iron and issubstantiallyV- shaped in cross section, the free edges of each of thepickets having the laterally, ex-

tending flanges 8 formed thereon in the manner clearly illustrated inFigure 3. The flanges 8 are adaptedto abut the front faces of the upperand lower longitudinally extending members 2 and 3 of the frame 1, thefastening bolts 7 employed for securing the pickets on the frameextending through the apex of each of the V-shaped pickets as alsoclearly illustrated in Figure 3. The purpose of the picket constructionof the character above described will hereinafter be more fullydescribed.

For the purpose of'supporting the fence at an incline, I provide thesupporting braces or legs 9 which are also formed of angle ironmaterial. The upper ends of the supporting members 9 are hingedlysecured to the ends of the frame as well as to the intermediate bracingmembers disposed between the upper and lower longitudinally extendingmembers '2 of the frame as at 10.

A hinged bracket 11 is hingedly secured at its respective ends to theframe and the supporting members 9 as clearly shown in Figure 2 of thedrawing whereby the support ing members 9 and the frame 1 will be set upin proper position when the hinged brackets 11 are extended.

The fence is adapted to be disposed adjacent a road or highway andparallelthereto, it being understood that the supporting members 9 aswell as the rear face of the frame and pickets face the road. The fenceis further secured in position adjacent the road or highway by theanchoring pins or stakes 12.

When the fence is set up, in position, it 1 will be apparent that thewind and air ourrents will strike the apices of the V-shaped fencepickets and travel in the direction of the arrows indicated in Figure 3of the drawing. The lateral flanges 8 on the free edges of the V-shapedpickets will cause the air currents to travel in the directionsubstantially at right angles to the direction in which the wind isblowing and will act as a barrier for the wind which is travelingbetween the pickets of-the fence whereby the wind or air currents willbe neutralized, thus-preventing the snow or the like from blowingthrough the fence and becoming banked on the road.

The provision of a snow fence of the above mentioned character, enablesthe same to be readily and easily assembled or disassembled and byconstructing the fence of angle iron material, the same is renderedstrong and durable. By removing the fastening bolts from the variousparts of the fence, the fencemay be disassembled in such a manner as toenable the parts comprising the same to be packed in a small amount ofspace thereby permitting the easy handling of the same.

bodiment of my invention, it is to be understood that various changes inthe s1ze, shape and arrangement of parts may be resorted frame inparallel spaced relation, each picket being substantially V-shaped incross section, lateral flanges on the free edges of each of the V-shapedpickets, said flanges abutting the aforementioned upper and lowerlongitudinal portions of the frame.

2. A fence comprising a rectangular frame, means for supporting the sameat an incline, and substantially V-shaped fence pickets secured on theframe in parallel spaced relation with respect to each other, lateralflanges formed on the edges of the V-shapedpickets, the lateral flangesof the several pickets cooperating with each other to cause air currentsto travel at substantially, right angles to the direction in which theair' currents are normally traveling to Vhile I have shown the preferredem neutralize the latter.

In testimony whereof I affix my signature.
